Demo update - Main story expanded

Summary

This relatively small update adds the next part of the main quest. You can now finally bring the Language Core back to the Exile, and get to know her a little. I wanted to add this to the demo sooner than the rest of the main content, since the Exile is a key character that needs to be properly introduced.

Changelog

• Main storyline: one new quest added, bring the Language Core to the Exile to start it. Spans about 7K words over multiple branches. Don’t go in unprepared unless you’re okay with failed stat checks!
